Dont start your build until you have all the before mentioned including spindle mount, as many times they will send you whatever they have at hand,

??? should I be concerned at this ??? !!!

Dont know, you decide. Finished my drawing in Sketchup and ordered everything. As i have some laser cut pieces i decided not to order them until i have all here to measure.

While all the ballscrews were machined to 0.01 and fit perfectly in the supports, they send me ball nut housings which they had at hand, so had to redraw a whole day. That affected the Z width also and the Z distance from gantry, so had to redraw there too. Also the spindle bracket i bought is quite bigger than at the ebay listings picture and wider by 20mm, so i could have bought 1 only, not 2, and if my Z was ready it would not fit, because of the fixing holes situation.

I mean, make the bead structure, but careful after that until you have the main parts at hand.

I am concerned that if you order, and they just send you what they have , what happens if you need a spare/replacement ? will it fit ? or not ?

Dont worry about that.

I am talking about ballnut housings and brackets. You will never need to replace that.

About the spindle, the only thing you could possibly replace there, are the 4 bearings, they sell them cheap at aliexpress. However possibly one day would be cheaper to buy a new one, depends how you value your time. 4 bearings cost ~20eur . I messed once with my spindle, but only because was desperate to finish an order, and because i want a bigger one, otherwise i would have simply bought a new one. Still works like a beast though.

About the ballscrews and nuts, i doubt you will ever need to replace any of them, but they are standard.

However things like HDT belts, HDT pulleys and so, i always buy extra, cause if i mess one, then have to pay extra shipping, they are cheap.
